Add Draft
– The Add Draft block applies draft to a mesh to aid manufacturing (specifically casting).
– We recommend using the Add Draft block for parts that have undergone topology optimization with the demold constraint. You can also apply a certain draft angle to a region using the Add Draft block for any surface mesh.
– The algorithm optimizes every face of the input shape to have the needed draft angle while ensuring the shape is only affected where required.
– Block Name: Add Draft
– Location: Beta Manufacturing
– Description: Applies a draft/taper angle to a mesh or a region of a mesh.
. Mesh: Mesh body to apply draft to. Draft will be applied to the entire body unless a region is specified.
. Demolding Direction: Vector representing the demolding direction. The draft will be applied in this direction.
. Draft Angle: Draft angle to apply to mesh.
. Max Iterations: The maximum number of iterations per attempt to converge each mesh element to comply with the desired draft. Increasing the number of iterations is beneficial for meshes with many faces.
. Max Attempts: The maximum number of attempts to achieve a mesh compliant with the draft angle. While a larger number of attempts increases solve time, it also increases the likelihood of creating convergent meshes on more complex parts (overhangs, larger draft angles, etc). As soon as all faces of the initial region achieve the input draft, the block finishes execution successfully.
. Smoothening: Value used to adjust the smoothness. Values can range from 0-1, with 0 turning off the smoothening function and 1 making the output shape as smooth as possible.
. Height Stability: Value to adjust the importance of maintaining height values (according to demolding direction). Values can range from 0-1, with 0 allowing unlimited movement and 1 allowing very little movement.
. Region: Optional input to limit the draft to being applied only to a specific region of the input mesh.
. Output: Mesh

Transform Material
– The Transform Material block enables you to transform a material from basis Source {X,Y,Z} to new basis Destination {X,Y,Z} with tensor omega_ij=dot(Destination_i,Source_j).
– You can use the Transform Material block to transform the Field-based material model for various simulation problems involving orthotropic material models. One of the primary use cases will be to enable the transformation of material models used in **Field Optimization**. e.g., Conformal ribbing and simulation with conformal orthotropic materials.
– Block Name: Transform Material
– Location: Beta Simulation
– Description: Transforms a material from basis Source {X,Y,Z} to new basis Destination {X,Y,Z} with tensor omega_ij=dot(Destination_i,Source_j).
. Material: The underlying material
. Source X: First component of the source frame
. Source Y: Second component of the source frame
. Source Z: Third component of the source frame
. Destination X: First component of the destination frame
. Destination Y: Second component of the destination frame
. Destination Z: Third component of the destination frame
. Output: Anisotropic Material
The image below shows an example of using a Transform Material block to rotate the material field by switching the Source and Destination vectors.

Await
– The Await block is used to execute once the ‘Wait For’ input is built and will produce the object in the ‘Return’ input as the output. This way, the Await block runs blocks one after the other in a serial order.
– The Await block combined with the Run Command block runs commands after input completion.
– Block Name: Await
– Location: Utilities General * Description: The **Await** block will execute once the *’Wait For’* input is built, and will produce the object in the *’Return’* input as the output. This way the **Await** block can be used to force blocks to run one after the other in serial order.
. Wait For: The data that is required to be available before executing the block
. Return: The value to be returned when the *’Wait For’* input has been executed
. Output: Any
The image below shows an example of using the Await block to wait to complete the **Export Mesh** block before running the Run Command block with the Python script.

Bug Fixes
– We fixed an issue with the Right Click Flood Fill selection that caused nTop to exit unexpectedly.
– We fixed an issue with the incorrect rendering of the Cylinder and Cone blocks when their axes were aligned with the Y-Axis.

nTopologyintroduced the concept of implicit modeling for mechanical design, which is an innovative, modern, and scalable way define parts and products. It has many benefits to end-users and companies, such as the elimination of model failures, speed of changes or iterations, and scalability to name a few. But implicit modeling enables so much more. In this informational session, we’ll explore a topic that is redefining product development – field-driven design. In short, field-driven design is a way for design, analysis, and manufacturing teams to overlay information into one engineering model. This approach enables orders of magnitude increase in design iteration speed and greatly improves collaboration between teams.
How Field-Driven Design Allows Engineers to Design for Additive Manufacturing
Watch this information session where we’ll define field-driven design, show examples of how it enables better knowledge sharing, and show how it promotes the development of more sophisticated, highly engineered products. You’ll also better understand how nTopology is addressing today’s engineering problems through its nTop Platform product.
nTopologywas founded in 2015 to enable engineers and designers to create any geometry – no matter how complex – and meet the requirements of high-performance products.
